Statewide Travel Forecasting Models


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 358: Statewide Travel Forecasting Models examines statewide travel forecasting models designed to address planning needs and provide forecasts for statewide transportation, including passenger vehicle and freight movements. The report explores the types and purposes of models being used, integration of state and urban models, data requirements, computer needs, resources (including time, funding, training, and staff), limitations, and overall benefits. The report includes five case studies, two that focus on passenger components, two on freight components, and one on both passenger and freight.

Analytical Travel Forecasting Approaches for Project-level Planning and Design


Book Description

"TRB's National Cooperative Highway Research Program (NCHRP) Report 765: Analytical Travel Forecasting Approaches for Project-Level Planning and Design describes methods, data sources, and procedures for producing travel forecasts for highway project-level analyses. This report provides an update to NCHRP Report 255: Highway Traffic Data for Urbanized Area Project Planning and Design. In addition to the report, Appendices A through I from the contractor's final report are available on CRP-CD-143. These appendices supplement this report by providing a substantial amount of companion data and information. The appendices also include the extended literature review, the detailed NCHRP Report 255 review, supplementary tables, a list of defined acronyms, and a glossary. Also included on CRP-CD-143 are spreadsheet demonstrations, and, for reference purposes, a tool developed by the North Carolina Department of Transportation to assess annual average daily traffic."--Publisher's description.

Texas Travel Forecasting Annotated Bibliography


Book Description

This bibliography is part of an on-going research project between the Texas Transportation Institute (TTI) and the Texas Department of Transportation (TxDOT). The bibliography has attempted to include all significant reports prepared by the Institute in support of urban transportation travel demand modeling and forecasting practice in Texas. An annotation is provided for those reports which still may be of interest to practitioners. Several reports which are now obsolete due to improvements in computer technology are included for completeness and historical interest. In addition several reports prepared by TxDOT which bear directly on travel demand modeling practice are included. The Department reports are not complete and users of this bibliography are requested to provide the Institute with copies of Department reports not presently included so that they may be included in future revisions. The bibliography is organized into six sections: trip generation, trip distribution, traffic assignment, travel surveys, air quality analysis, and overview. Reports are placed in each section according to the phase of modeling covered by the report. However, since the modeling phases are interdependent, most reports will cover aspects of more than one phase. Reports which clearly cover more than one modeling phase are placed in the overview section.







Improving Motor Carrier Safety Measurement


Book Description

Every year roughly 100,000 fatal and injury crashes occur in the United States involving large trucks and buses. The Federal Motor Carrier Safety Administration (FMCSA) in the U.S. Department of Transportation works to reduce crashes, injuries, and fatalities involving large trucks and buses. FMCSA uses information that is collected on the frequency of approximately 900 different violations of safety regulations discovered during (mainly) roadside inspections to assess motor carriers' compliance with Federal Motor Carrier Safety Regulations, as well as to evaluate their compliance in comparison with their peers. Through use of this information, FMCSA's Safety Measurement System (SMS) identifies carriers to receive its available interventions in order to reduce the risk of crashes across all carriers. Improving Motor Carrier Safety Measurement examines the effectiveness of the use of the percentile ranks produced by SMS for identifying high-risk carriers, and if not, what alternatives might be preferred. In addition, this report evaluates the accuracy and sufficiency of the data used by SMS, to assess whether other approaches to identifying unsafe carriers would identify high-risk carriers more effectively, and to reflect on how members of the public use the SMS and what effect making the SMS information public has had on reducing crashes.
